Is there any way to use multiple tuners of Pi TV HAT together on one Raspberry Pi?
Something like cluster to make it octa tuner ;)
To be able to watch/record from 4 multiplexes at the same time.
No, not easily anyway. It uses SPI, each one would have to use a different CE pin. Even then they are all sharing that one bus.

IMHO, this is one of those, “is it really worth the effort” deals.
There is no quad USB DVB-T2 card :(
And if you get four tuners that si four TV coaxes, loots of cables/dongles,
one would need perhaps USB HUB if you wanted external HDD as well and it’s getting more complex.
Quad would suite most families, “octa” would be best, but at what price …
